Takuya Kitazawa created HIVEMALL-162:
----------------------------------------

             Summary: Support `l1_normalize` for feature vector
                 Key: HIVEMALL-162
                 URL: https://issues.apache.org/jira/browse/HIVEMALL-162
             Project: Hivemall
          Issue Type: New Feature
            Reporter: Takuya Kitazawa
            Assignee: Takuya Kitazawa
            Priority: Minor


Similarly to {{[l2_normalize|https://github.com/apache/incubator-hivemall/blob/master/core/src/main/java/hivemall/ftvec/scaling/L2NormalizationUDF.java]}} UDF, we can support L1 normalization, even though it can be achieved by standard HiveQL syntax (i.e.,
 something like {{col / sum(col)}}).
